The 43 DC's are pretty cheap too. My 3208 Cats dont run on a plane to well and I have turbos. They are only 300 hp. Thats why I just poke along at 7.5 kts @ 3.5-4 gal/hr. Its nice and quite at that speed too. The only thing I'm missing is a big shrimp net to pull.
Lol, but I'm in lust with a 53, 20 kts with a NA is out of the question.... 14, 16 on the very outside. But yes, 7-8 and you can still hear yourself talk over the sucking fuel noise.
